  What kind of information should be collected when events occur in various work sites such as manufacturing, construction, civil engineering, inspection and maintenance, and transportation differ depending on each site. Thus, an information gathering system suitable for one site may not be suitable for another site. However, building an optimal system for each site is uneconomical.

  In addition, one important purpose of information gathering at the time of occurrence of an event is elucidation of the cause of occurrence of the event. In particular, when an adverse event occurs, elucidation of the cause is strongly required for future prevention. However, if the fact that could not be collected by a worker or equipment directly involved in the occurrence of an event is the cause of the occurrence of the event, it is difficult to elucidate the cause. A system that collects all the information at every point on the site will eliminate this problem, but such a system is uneconomical and impractical. A system that can economically collect data related to event occurrence from multiple fields is desired.

  One of the objects of the present invention is to provide a work information system that can be applied to different work sites.

  Another object of the present invention is to provide a task information system which can economically collect data related to event occurrence from multiple fields.

  According to one embodiment of the present invention, there is provided a work information system for collecting data related to events each occurring at one or more work sites. At each work site, there may be one or more data collection systems, each equipped with one or more workers, and each data collection system collects one or more types of data about each worker and / or the surrounding environment. .

  And this work information system is provided with a data server which receives data collected by the one or more data collection systems. This data server defines a detection criterion that defines which event is to be detected based on what received data, the data received from the one or more data collection systems, and the above detection criterion. An event detection unit that detects each defined event, a sorting criterion that defines which data of received data is to be sorted corresponding to each event defined in the detection criteria, and each event by the event detection unit When data is detected, based on the selection criteria, the data selection unit selects data corresponding to each detected event from received data, and the data selected by the data selection unit as detected events. A condition recording unit for associating and recording, a data output unit for outputting the data recorded by the event recording unit out of the data server, and a condition for setting detection criteria and sorting criteria for each work site It can have and tough.

  According to the work information system configured as described above, data collected by the data collection system of one or more workers is received by the data server at each work site. Then, in the data server, based on which data of the data received from each work site, a detection standard that defines what event is detected, and which data of received data when each event is detected It is possible to set, for each work site, a sorting criterion that defines whether to sort and record. Then, based on detection criteria and sorting criteria set for each work site, detection of an event for each work site and sorting and recording of data are performed.

  The work information system configured in this way is applicable to different work sites having different requirements in terms of what events should be detected and what data should be recorded at the time of event detection.

  The above-mentioned data server is notified by the notification standard that defines what report should be sent to which destination in response to at least one emergency event of the one or more events defined in the detection criteria, and the event detection unit When an emergency event is detected, a report corresponding to the detected emergency event is created based on the notification standard, and the emergency report unit transmits the report to a destination corresponding to the detected emergency event; You may have. Then, the condition setting unit may be configured to be able to set the notification standard for each work site.

  According to such a configuration, it is possible to set, for each work site, a notification standard that defines which report (for example, which worker) is to be sent when a certain emergency event occurs. Then, based on the notification standard set for each work site, when an emergency event occurs, an appropriate notification is provided to an appropriate destination.

  In this way, in addition to data collection at the time of occurrence of an event, notification to a relevant person or a related device when any emergency event occurs is also executed automatically and in the manner of each work site. Thus, this work information system can be adapted to different work sites.

  When the condition setting unit described above sets the detection criteria and the sorting criteria for each work site, the detection criteria are based on the first data received from the first data collection system of the first worker. Define that the first event is to be detected, and the sorting criteria correspond to the first event from the second data collection system of the second worker different from the first worker It may be configured such that it may be defined that the second received data is to be sorted.

  According to this configuration, when an event is detected based on data from a data collection system of a worker (first worker), another worker (second worker) other than the worker It is possible to sort and record data from the data collection system of For example, if each data acquisition system is equipped with a camera that captures the surrounding situation, when one worker (the first worker) causes an event, another worker (the second worker) It is possible to sort and record image data captured by the camera of.

  Thus, for example, a situation not known to the person who caused the event (for example, the situation behind the person who did not notice the worker who caused the accident, how to move the person's body, etc.) This can be grasped by referring to the data observed by the workers of. Therefore, analysis such as event cause may be more accurate. That is, data collection from multiple fields useful for cause analysis of events etc. can be performed economically by using existing resources at work sites of other workers.

  When the condition setting unit described above sets the detection standard and the notification standard of each work site, the detection standard is based on the first data received from the first data collection system of the first worker. It defines that a first emergency event is to be detected, and the notification standard includes, in response to the first emergency event, a second worker other than the first worker, the second worker. It may be configured to be included in the destination.

  According to this configuration, when an emergency event occurs with respect to a certain worker (the first worker), it is detected that a notification is sent to another worker (the second worker) other than the worker. You can set criteria and notification criteria. Thus, for example, when an accident occurs to a certain worker, a notification can be sent to the appropriate other worker to instruct appropriate accident handling or injury relief. The mode of this notification can be set according to the circumstances of each work site.

  The data server may further have a group setting that defines a group to which a plurality of workers at each work site belong. Then, the condition setting unit may allow the second worker to include one or more other workers belonging to the same group as the first worker defined in the group setting. May be configured.

  According to such a configuration, when an event occurs that is a worker belonging to a group, data collected by other workers belonging to the same group may be recorded, or other workers belonging to the same group It is possible to send an appropriate report. The setting for that can also be adjusted according to the circumstances of each work site.

  The data collection system of each worker may have a position sensor that detects the position of each worker. Then, the above-mentioned condition setting unit defines the relative position range with respect to the first worker, so that the other one or more workers located in the defined relative position range are the second worker described above. May be configured to be included.

  According to such a configuration, when an event occurs that is a worker at a certain position, data collected by other workers within a certain relative position range (for example, a certain distance range) with respect to the worker Can be recorded, or a notification can be sent to other workers within the relative position range. The setting for that can also be adjusted according to the circumstances of each work site.

  At the work site, in addition to workers, one or more peripheral objects (eg, devices, machines and objects to be worked, buildings, tools and machines operated by workers, machines and robots working with workers, etc.) ) May be present. Each peripheral object may be adapted to detect data about the peripheral object. The above data server may then be adapted to further receive data detected by its surrounding objects. In that case, the above-mentioned condition setting unit may be configured to be able to include the data received from the peripheral object in the data respectively defined in the detection standard and the sorting standard.

  According to such a configuration, not only data collected by the worker's data collection system but also data detected by devices, machines, etc. (nearby objects) present around the worker are used to detect an event. Or, data from surrounding objects can be recorded at the time of event detection. Depending on the situation of each work site, it can be set which data from which peripheral objects are to be used.

  As a result, data collection from multiple fields useful for elucidating the cause of an event can be economically performed using existing peripheral objects at the work site.

  Also, the data collection system of each worker may have headgear worn by each worker on the head. The headgear may have a camera for capturing the surrounding situation viewed from the head of each worker and a microphone for sensing the sound emitted from each worker. Then, the above-mentioned condition setting unit can define, as a detection criterion, that a specific event is to be detected based on a voice word grasped from voice data from a microphone, and respond to the particular event as a selection criterion. It may be configured such that it can be defined that the image data from the camera is to be sorted.

  According to such a configuration, it is possible to detect an event based on the speech of each worker. For example, when words such as "poor", "affirmation", and "dangerous" are issued, it is possible to detect an event corresponding to a kind of so-called hiyari hat. Since the worker's utterance may include words that can estimate the occurrence of various events, detecting events based on the utterance may be effective at any work site. What kind of language to use may be set for each action site.

  Also, when an event is detected based on a spoken word, it is possible to sort and record image data captured from headgear of the head of the worker who issued the word or the head of another worker. It is meaningful to record such a video as the video seen from the position of the head of each worker may contain information that is likely to be useful for improving the working method of the worker in the future.

  Furthermore, by using headgear to collect voice and image data, workers can freely concentrate on their work with both hands without worrying about data collection.

  Further, the data collection system of each worker may further include a portable personal computer (abbreviated as a portable PC) carried by each worker in addition to the headgear worn by the worker on the head. The portable PC can communicate with the headgear and can also communicate with the data server described above, and may be configured to receive audio data and image data from the headgear and transmit them to the data server. As a portable PC, it is possible to use an existing general-purpose information communication terminal such as a so-called smartphone or a tablet type terminal in which an application program for a data collection system is installed.

  According to such a configuration, by utilizing the communication function and the information processing function of the portable PC, the configuration of the headgear worn by the worker on the head can be simplified, and accordingly, the cost and weight of the headgear Can be reduced. In addition, it is possible to reduce the number of delicate parts mounted on the headgear that would be used harshly, and to reduce the failure rate of the headgear.

  The headgear 9 is a head-mounted electronic device that can be worn by the worker 3 on the head, and an example of its configuration will be described later with reference to FIG. Headgear 9 makes worker 3 especially aware of data on worker 3 and its surrounding environment obtained at the position of worker 3 while ensuring that worker 3 can use both hands freely. Can be collected without

  For the mobile PC 11, for example, general-purpose mobile information communication terminals such as so-called smart phones, mobile phones, and tablet terminals can be used. By installing a predetermined application program in such a portable information communication terminal, the portable information communication terminal functions as the portable PC 11 for the work information system 1. Alternatively, the mobile PC 11 dedicated to the work information system 1 may be prepared.

  At least one data server 13 is present at a location remote from the worker 3 or at a location remote from the work site. The data server 13 collects data relating to various events occurring at the work site from the work site and the worker 3 in real time, records those data, and works various information based on those data Have a role to provide to staff 3 and other related parties. The data server 13 can mutually communicate data with the mobile PC 11 of each worker 3 through a predetermined communication network.

  The data server 13 also communicates with specific peripheral objects 7 in or near the work site wirelessly or by wire, and data on the state of the peripheral objects 7 detected by those peripheral objects 7 in real time It may be configured to be able to collect. For example, at a manufacturing site, tools or machines such as a nut runner operated by each worker 3, a manufacturing facility such as a robot or a transport device that cooperates with the worker 3, or a device to be worked The data server 13 may be configured to collect predetermined data from a machine or the like.

  FIG. 2 is a front view showing a schematic configuration example of the head gear 9.

  As shown in FIG. 2, the headgear 9 is configured using, for example, a helmet 15 (or a work cap) that the worker 3 should wear on the head at the work site, but this is an example, and it is not always necessary. It doesn't have to be. The helmet 15 is provided with a transparent shield (visor) 17 for protecting the face. The shield 17 may function as a display 18 for displaying (or projecting onto) an image or text. Alternatively, a display 18 may be provided on the helmet 15 (not shown) as a device separate from the shield 17 for showing an image or text to the worker 3.

  The helmet 15 is a camera 19 (preferably a compound eye camera capable of measuring the distance to an object in a photographed image) for capturing a moving image or a still image of a space area in front of the head of the worker, and other workers A set of conversational microphones 21 and conversational speakers 23 for conversations with three or other people is provided. Furthermore, the helmet 15 is provided with a main device 25 in which various sensors (to be described later), an information processing device that performs data processing, and a communication device that performs wireless communication with the portable PC 11 are installed. Be done. Furthermore, the helmet 15 is provided with a battery 27 as a power source for various electronic devices of the helmet 15.

  Refer back to FIG.

  As described above, the headgear 9 includes the display 18, the camera 19, the conversation microphone 21, the conversation speaker 23, and the main device 25. And main device 25 has various sensors, such as position sensor 35, direction sensor 37, acceleration sensor 39, sight line sensor 41, one or more vitile sensors 43, and one or more environment sensors 45, etc. .

  The camera 19 shoots the front area of the head 47 of the worker 3, so that the photographed image includes the limbs 51 of the worker 3 and a part of the body 49 and the surroundings of the head 47 of the worker 3 There is a possibility that an object 7 (for example, a work target or an object near the work), and a figure of another worker 3 within the range viewed by the worker 3 may be shown.

  It is desirable that the camera 19 continuously shoots moving images constantly while the worker 3 is working, but instead, still images may be shot intermittently intermittently, or for operation by the worker 3 Depending on the situation, you may shoot a movie or shoot a still image.

  The position sensor 35, the azimuth sensor 37 and the acceleration sensor 39 respectively indicate the three-dimensional position (latitude, longitude, altitude) of the head 47 of the worker 3, the direction in front of the head 47, and the three-dimensional acceleration of the head 47 (or Measure the inertial force). The position sensor 35 may be, for example, a GPS receiver, or a combination of a GPS receiver and the direction sensor 37 and the acceleration sensor 39 described above.

  The sight line sensor 41 observes the movement of the eye 53 of the worker 3 and measures the position of the viewpoint of the worker 3 (where it is seen). One or more vital sensors 43 measure one or more vital signs 59 of the worker 3 (for example, body temperature, pulse rate, respiration rate, blood pressure, blood glucose level, etc.). The one or more environmental sensors 45 measure one or more state values (for example, air temperature, humidity, barometric pressure, gas component and concentration, noise level, or wind speed) included in the environmental state 5.

  It is desirable that these sensors 35 to 45 continue sensing at all times while the worker 3 is working, but instead, sensing may be repeated intermittently or according to the operation of the worker 3 You may do sensing.

  The main device 25 transmits, in real time, moving image data or still image data taken by the camera 19 and various measurement data obtained by the sensors 35 to 45 to the portable PC 11 of the same worker 3. The main device 25 also performs processing of voice conversation between the worker 3 and other workers and people using the conversation microphone 21 and the conversation speaker 23 (for example, the portable PC 11 performs voice data from the conversation microphone 21 in real time). Transmission, and outputting voice data from the portable PC 11 in real time to the conversation speaker 23). The main device 25 also displays the image data and text sent from the portable PC 11 on the display 18 in real time.

  The portable PC 11 includes a main device 51, a position sensor 53, an acceleration sensor 55, a voice recognition unit 57, a voice synthesis unit 59, and the like.

  The position sensor 53 and the acceleration sensor 55 of the portable PC 11 measure the three-dimensional position (latitude, longitude, altitude) and acceleration of the portable PC 11, respectively. Since the worker 3 wears the portable PC 11 during work, the position and acceleration measured by the position sensor 53 and the acceleration sensor 55 substantially indicate the position and acceleration of the body 49 of the worker 3. The position sensor 53 may be, for example, a GPS receiver, or may be a combination of a GPS receiver, an azimuth sensor, and the acceleration sensor 55.

  The speech recognition unit 57 receives speech data, performs speech recognition, and outputs text data. The speech synthesis unit 59 inputs text data, performs speech synthesis, and outputs speech data.

  The main device 51 of the portable PC 11 receives moving image data, still image data, various measurement data, and audio data sent from the headgear 9 and transmits those data to the data server 13 in real time. Further, the main device 47 sends the position data and acceleration data measured by the position sensor 53 and the acceleration sensor 55 in the portable PC 11 to the data server 13 in real time.

  In addition, when voice conversation is being performed between the worker 3 and another worker 3 or another person, the main device 47 sends voice data from the headgear 9 to the portable PC 11 of the conversation partner in real time. Also, the voice data from the portable PC 11 of the conversation partner is sent to the headgear 9 in real time. In addition, when text conversation is performed between the worker 3 and another worker 3 or another person, the main device 47 sends the text data from the headgear 9 to the portable PC 11 of the conversation partner in real time Also, text data from the portable PC 11 of the conversation partner is sent to the headgear 9 in real time.

  Further, main device 47 receives voice data sent from headgear 9, sends the voice data to voice recognition unit 55 in real time, and as a result voice recognized text data output from voice recognition unit 55 , Sends to the data server 13 in real time. Furthermore, the main device 47 sends text data (for example, text data of a message of an emergency report described later) sent from the data server 13 to the headgear 9 in real time and / or voices the text data in real time. The voice data is sent to the synthesis unit 59, and as a result, the voice data output from the voice synthesis unit 59 is sent to the headgear 9 in real time.

  The data server 13 has functional elements such as a communication device 61, a condition setting unit 63, a short-term storage unit 65, an event detection unit 67, a data selection unit 69, a long-term storage unit 71, a data output unit 73, and an emergency notification unit 75. The data server 13 also has information elements such as detection criteria 81, emergency criteria 83, sorting criteria 85, group settings 87, work schedules 89, notification criteria 91, and event records 93.

  The communication device 61 of the data server 13 receives various data sent from the portable PC 11 of each worker 3 and transmits necessary data (for example, a message of an emergency notification to be described later) to each portable PC 11 Do. The communication device 61 may also be in data communication with some of the peripheral objects 7 present at the work site.

  The condition setting unit 63 detects, for each work site, what kind of event is detected, what data is recorded about the detected event, and what kind of message or control signal regarding the detected event It sets the operating condition of whether to notify the worker or which device. The condition setting unit 63 also sets the work schedule at each site. The items set by the condition setting unit 63 are registered in the detection standard 81, the emergency standard 83, the sorting standard 85, the group setting 87, the work schedule 89, and the notification standard 91.

  The condition setting unit 63 sets, for example, the portable PC 11 or other information processing terminal from a specific person (for example, a specific worker 3, a specific administrator, etc.) who has been given the right of setting the conditions of the site in advance When the user logs in through the field, he / she receives the input of setting items from that particular person, and the detection criteria 81, emergency criteria 83, sorting criteria 85, group settings 87, work schedule 89, or that of the site described in the notification criteria 91. Edit (add, delete or change) settings of various conditions.

  The short-term storage unit 64 stores various types of collected data received from the portable PC 11 of each worker 3 for a predetermined short period, and erases the stored data when this storage period has elapsed. The storage period is determined by how much time from the time of occurrence of the predetermined event has occurred to record relevant data retroactively. For example, in the case of recording data from 10 minutes before the event occurrence time, the storage period can be 10 minutes. The storage period can be set for each site by the condition setting unit 63.

  The event detection unit 67 examines the data stored in the short-term storage unit 65 to determine whether a predetermined event has occurred, that is, detects the occurrence of the predetermined event. Detection criteria 81 and emergency criteria 83 are used to make event detection or event occurrence determinations.

  The detection criteria 81 define, for each type of event to be detected, a type of data to be examined and a detection condition as to which condition the data should be judged to be an event occurrence. Of the event types set in the detection criteria, the emergency criteria 83 define which event type is an emergency event (that is, an event for which a prompt coping action should be performed). The definition content of the detection standard 81 can be set for each site by the condition setting unit 63.

  The event detection unit 67 continuously checks whether the data stored in the short-term storage unit 65 satisfies any of the detection conditions described in the detection criterion 81, and a certain detection condition is satisfied. It is determined that an event of an event type corresponding to the detection condition has occurred. When the occurrence of an event is detected, the event detection unit 67 notifies the data classification unit 69 of the event type of the event, and determines whether the event type is an emergency event based on the emergency criteria 83. . If it is determined that an emergency event has occurred, event detection unit 67 notifies emergency notification unit 75 of the event type. The emergency criteria 83 define which of the event types described in the detection criteria 81 correspond to emergency events. The definition content of the emergency standard 83 can be set for each site by the condition setting unit 63.

  When a certain event is detected, the data sorting unit 69 sorts and reads out data related to the event type from the short-term storage unit 65. For this sorting, sorting criteria 85 are referenced. The sorting criteria 85 defines, for each event type, a data type to be sorted and a data source (that is, where the sensed data should be sorted out). The definition content of the sorting standard 85 can be set for each site by the condition setting unit 63.

  When a certain event occurs, if a certain worker group is defined in the sorting criteria 85 as a data source for the event type, the data sorting unit 69 refers to the group setting 87 and determines which worker Decide if the data from 3 should be sorted out. In the group setting 87, in order to identify a group of workers 3 working at each site (that is, a team, a belonging department, etc.), a worker 3 who is a member of each group, and a portable PC 11 used by the worker 3 Information is defined. The definition content of the group setting 87 can be set for each site by the condition setting unit 63.

  The data sorted by the data sorting unit 69 includes data of a work schedule 89 prepared in advance, in addition to the data stored in the short-term storage unit 64. The work schedule 89 describes a work schedule set in advance for each site, each worker group, or each worker. The contents of the work schedule 89 can be set for each site by the condition setting unit 63.

  The long-term recording unit 71 stores the sorting data related to the occurrence event sent from the data sorting unit 69 as an event record 93 related to the occurrence event in the long term.

  The data output unit 73 reads out the event record 93 from the long-term recording unit 71 when output of the event record 93 is requested from an appropriate information processing terminal or user outside the data server 13, and uses it as the information processing terminal of the request source or Provide to the user. The output event record 93 can be analyzed, for example, to clarify the cause of occurrence of the event, to improve the work process, or to transmit skills.

  When an emergency event occurs, the emergency notification unit 75 generates a message, auxiliary information and / or a control signal for immediately dealing with the emergency event, and the worker who should handle it through the communication device 61. 3 (a portable PC 11 used by the worker 3) and / or a surrounding object 7 is notified. At that time, the emergency notification unit 75 refers to the notification standard 91 to determine what information is to be notified to which worker 3 or which main variable object. In the notification standard 91, the destination of the notification and the content of the notification are defined for each event type of the emergency event. When a worker group that is a notification destination of the event type that has occurred is defined in the notification standard 91, the group setting 87 is referred to, and the worker 3 belonging to the worker group is identified as a specific destination. Ru. The definition content of the notification standard 91 can be set by the condition setting unit 63 for each site.

  FIG. 3 shows a setting example of the detection reference 81 and the emergency reference 83.

  As exemplified in FIG. 3, data types and detection conditions are defined in the detection criteria 81 for each event type (illustrated by an identification code such as “001” in the figure). The data type indicates which data is to be used to determine the occurrence of the event (to detect the event). The detection condition indicates which condition the data meets if it is determined that the event has occurred (the event is detected). Also, the emergency criteria 83 define, for each event type, whether it is an emergency event (for example, a value “1”) or not (for example, a value “0”).

  In FIG. 3, for example, for the event type “001”, the data type is “person: spoken word”, and the detection condition is “(Yab) + (Bad) + (Sort)” (here, the symbol “ + "Means disjunction, which is the same as other conditions). This is about the worker 3 person when the word (that is, the speech recognition result of the voice data of the worker 3) which a certain worker 3 utters is "yabai", "bad" or "it has fallen". It means that it is determined that an event of the event type "001" (for example, a kind of so-called near miss) has occurred. In the example of FIG. 3, this event type "001" is not set as an emergency event.

  Further, for example, for the event type “004”, the data type is “person: head gravity acceleration; then head movement speed”, and the detection condition is “≦ 2.0 m / sec2; (≦ 3 cm / sec) × (≧ 30 sec) (Here, the symbol “x” means a logical product, which is the same as other conditions). This is because the gravitational acceleration of the head of a certain worker 3 (as measured by, for example, the acceleration sensor 39 of the head gear 9) falls to “≦ 2.0 m / sec 2” (that is, it may have fallen), The state in which the movement speed of the head (for example, calculated from the measurement data of the position sensor 35 of the headgear 9 and the acceleration sensor 39) is "≦ 3 cm / sec" continued for "≧ 30 sec" (that is, the head is 30) In the case where almost no movement continues for more than a second), it is determined that an event of the event type “004” (for example, a fall or a temper to lose the person's awareness) has occurred for the worker 3 himself means. In the example of FIG. 3, this event type "004" is set as an emergency event.

  Also, for example, for the event type “005”, the data type is “nut runner 01” and the detection condition is “insufficient torque”. This is because, when the nut runner of the identification number "01" used for bolting in the peripheral object 7 issues an error signal indicating "insufficient torque", the nut runner (the worker 3 who uses the nut runner is previously If it is specified, it means that it is determined that an event of the event type “005” (for example, a kind of work error) has occurred for the worker 3). In the example of FIG. 3, this event type "005" is not set as an emergency event.

  Further, for example, for the event type "006", the data type is "other company: spoken language", and the detection condition is "(" identity name ") x ((dangerous) + (bad))". When the word issued by a worker 3 is the name of another worker 3 and "dangerous" or "poor", an event of the event type "006" for the other worker 3 whose name is called For example, it means that it is determined that a kind of so-called "missing" has occurred. In the example of FIG. 3, this event type "006" is not set as an emergency event.

  As described above, the events defined in the detection criteria 81 and the emergency criteria 83 are automatically detected based on the data collected by the worker 3 or the peripheral object 7.

  Here, it should be noted that the items defined in the detection criteria 81 and the emergency criteria 83 can be arbitrarily set by the user for each work site. Then, depending on the setting of the user, not only when an event related to each worker 3 is detected from the data collected at the position of the worker 3 himself, but also data detected at the position of the other worker 3 (For example, event type "006" in FIG. 3), or may be detected from data collected by the peripheral object 7 (for example, event type "005" in FIG. 3) It is. This enables flexible event detection according to the circumstances and needs of the site.

  FIG. 4 shows an example of setting of the sorting reference 85. Although FIG. 4 shows only a setting example for one event type "001", not only that, the settings for all event types defined in the detection criteria 81 described above may be included in the sorting criteria 85. .

  As illustrated in FIG. 4, the sorting criteria 85 define, for each event type, the type and source of data to be sorted when the event is detected, and the period for which the data should be recorded.

  For example, in FIG. 4, for the event type "001", "microphone sound", "speaker sound", "camera image", "position", "head direction", "line of sight", "neighboring object" as data types Data, job schedule, etc. are defined. And as a data source, "microphone sound", "speaker sound" and "gaze" are defined as "person", and "camera image", "position", "head direction" and "work schedule" Is defined as “(person) + (same group) + (distance ≦ 20 m)”, and “neighboring object data” is defined as “(distance ≦ 20 m)”. Further, as the recording time, "scheduled to work" is defined as "one day on the day", and "± 10 minutes" is defined for other data.

  This setting example means that when an event of the event type "001" is detected for a certain worker 2, the following data is selected.

  That is, the voice of the worker 3 himself (voice data output from the conversation microphone 21), the voice heard by the person (voice data input to the conversation speaker 23), the image taken by the camera 19 of the person, the person Position (the three-dimensional position data measured by the position sensor 35), the direction of the head of the person (direction data measured by the direction sensor 37), the line of sight of the person (viewpoint data measured by the line of sight sensor 41), and the person The work schedule (obtained from the work schedule 89) is selected.

  In addition, camera images, three-dimensional positions, head orientations from other workers 3 belonging to the same worker group as the person and other workers 3 located within a distance of 20 m from the position of the person And work schedule is also sorted out. Furthermore, the data sensed by the peripheral object 7 located within a distance of 20 m from the position of the user is also sorted out.

  Of the various data selected above, one day's worth of data for “scheduled work” for “scheduled work”, and for other data, from 10 minutes before to 10 minutes after event time The data for the period is sent to the long-term recording unit 71 and recorded in the event record 93 associated with the detected event.

  Thus, when an event is detected, data possibly related to the detected event is sorted according to the definition of the sorting criteria 85 for a defined period of time and saved as an event record 93.

  It should be noted here that the user can arbitrarily set the definition content of the sorting standard 85 for each site. Then, depending on the setting of the user, not only the data collected at the position of the worker 3 but also the data collected at the position of the other worker 3 or the surroundings of an event that occurred for a certain worker 3 The data collected at object 7 may also be recorded.

  By this, the acquisition source of the data recorded regarding the occurrence event is expanded in many directions, and it becomes possible to perform analysis such as elucidation of the cause later in more detail and accurately. For example, when an event occurs in which a worker 3 is injured due to a collision with a surrounding object 7, not only data collected at the worker 3 himself, but also other members who were around the worker 3 Data collected at workers 3 (for example, the camera image of another worker 3 may show the appearance of the colliding worker 3 and the surrounding object 7 before and after the collision), the surroundings The cause of the collision is also recorded by recording the data collected by the object 7 (from which you may know in detail how the surrounding object 7 that collided was acting at the time of the collision). The movement of the person's body or the unexpected movement of the surrounding object 7 that could not be found only by the data collected at the worker 3 himself may be elucidated more accurately .

  FIG. 5 shows a setting example of the group setting 87.

  For example, when a worker group is defined as “same group” as a data source in the above-described sorting standard 85 or as a report destination in the report standard 91 described later, the group setting 87 is a task belonging to the group It is used to identify the member 3.

  As illustrated in FIG. 5, in the group setting 87, for each worker group, the identification code of the group (group ID), the identification code of the worker 3 of the member of that group (member ID), The status (member status) and name (member name) in the group, the communication address (portable PC address) of the portable PC 11, the identification code of the portable PC 11 (portable PCID), the identification code of the headgear 9 (headgear ID), etc. are defined. Ru. Although only one group setting example having the group ID “G01” is shown in FIG. 5, if there are a plurality of groups, all settings of those groups can be registered in the group setting 87.

  The contents of the group setting 87 can also be arbitrarily set by the user for each site. Therefore, it is possible to flexibly respond to the situations and needs of the site.

  FIG. 6 shows a setting example of the notification standard 91. In FIG. 6, only a setting example for one event type “004” corresponding to an emergency event is shown, but not only setting for the event types of all emergency events defined in the above-described emergency standard 83 is , May be included in the notification criteria 91.

  As exemplified in FIG. 6, the notification standard 91 includes, for each event type, the destination of the notification, the means for notification (the type of signal or data used for the notification), and the content of the notification (message, data, or operation constituting the notification). Etc).

  For example, in FIG. 6, for the event type “004” (in the example shown in FIG. 3 described above, the operator 3 falls or "There is a" speaker voice "as the means of reporting, and" "Are you OK? ..." as the content of the report. This is the conversation speaker of the worker 3 who caused the fall or taunt In 23, it means sending a voice message "Are you OK?" To ask the person the current status.

  In addition, there are "(administrator) + (the same group) + (≦ 20m distance)" as another report destination, and "speaker voice", "display", "individual position", "speaker voice" in the report means. There is a fear that "the person's name" is abnormal in the content of each report. Please check and take action such as rescue. ... "," user's own camera image "," user's own position: map and relative position display "," microphone voice: (user's own) + (the same group) + (≦ distance 20 m) ". This is a predetermined administrator And "person's name" is likely to be abnormal for the other person 3 who belongs to the same group as the person or is within 20 meters of the same group. Please check and take action such as rescue. The voice message “...” is notified from the conversation speaker 23 of each person, and the photographed image of the camera 19 of the person is displayed on the display 18 of each person, and the map showing the three-dimensional position of the person and the relative position display In addition, the microphone sound of the conversation that those people interact with each other is sent to the speaker 23 of each person, and the current situation of this accident is notified to the surrounding people as accurately as possible to cope with the rescue etc. It means to urge.

  Another notification destination is "AED", the notification means is "indication light", and the notification content is "lighting". This means that an indicator light is turned on for an installation station of an AED (automatic external defibrillator), which is one of the peripheral objects 7, to notify the surrounding people of the location of the AED.

  The contents of the notification standard 91 can also be set arbitrarily by the user for each site. Depending on the setting of the user, when an emergency event occurs, an appropriate report is sent to the person or other worker 3 or the related peripheral object 7 depending on each site, and the appropriate response is taken. Be directed or guided.

  FIG. 7 shows an example of the data configuration of the event record 93.

  As shown in FIG. 7, the event record 93 related to a certain occurrence event includes, for example, the identification code (event ID) of the event, the event type, and the occurrence date and time. Furthermore, in the event record 93, for example, the identification code (identity ID) of the worker 3 (person) directly involved in the occurrence of the event (note that the surrounding object 7 instead of the worker 3 is directly involved in the occurrence In this case, the identification code of the peripheral object 7), the data source of each data recorded, the data type, and each recorded data file etc. associated with the lexical information of these data by the file path are included. Be

  FIG. 8 shows an example of the control flow of the headgear 9 of each worker 3 during work.

  As shown in FIG. 8, the headgear 9 uses the camera 19, the conversation microphone 23 and the other sensors 35 to 45 mounted thereon to display the state or operation of the worker 3 wearing the headgear 9, the peripheral image And sensing of the surrounding environmental condition 5 (step S1), and transmit the sensed data to the portable PC 11 of the same worker 3 (S2). This operation is repeated continuously.

  In addition, the headgear 9 receives image data, voice data, text data, etc. to be provided to the worker 3 from the portable PC 11 (S3), and the received data corresponds to an output device such as the display 18 or conversation speaker It outputs to 23 etc. (S4). This operation is repeated continuously.

  FIG. 9 shows an example of the control flow of the portable PC 11 of each worker 3 during work.

  As shown in FIG. 9, the portable PC 11 receives data sent from the headgear 9 of the same worker 3 (S11), and sends the received data to the data server 13 (S12). At this time, the received voice data is voice-recognized, and text data as a voice recognition result is also sent to the data server 13. This operation is repeated continuously.

  In addition, the portable PC 11 performs sensing with the sensors 53 and 55 mounted thereon (S13), and sends sensed data to the data server 13 (S14). This operation is repeated continuously.

  Furthermore, the portable PC 11 receives image data, voice data, text data, etc. for the headgear 9 sent from the data server 13 (S15), and sends those data to the headgear 9 of the same worker 3 (S16) . At this time, the portable PC 11 converts certain text data received into speech data by speech synthesis and sends the speech data to the headgear 9. This operation is repeated continuously.

  Furthermore, the portable PC 11 receives the image data, voice data, text data, etc. for the portable PC 11 sent from the data server 13 (S17), and outputs these data to the corresponding output device of the own device, for example, Output to a speaker or speaker (S18). This operation is repeated continuously.

  FIG. 10 shows an example of the control flow of the data server 13.

  As shown in FIG. 10, the data server 13 receives data sent from the portable PC 11 of one or more workers 3 of each work site and / or one or more peripheral objects 7 (S21), and received The data is stored in the short-term storage unit 65 (S22). This operation is repeated continuously.

  The received data 101 stored in the short-term storage unit 65 is stored there for a predetermined short period. During the storage period, the data server 13 checks the received data 101 against the detection reference 81 to determine whether an event defined in the detection reference 81 has occurred (S23). As a result, when it is determined that one of the defined events has occurred (Yes in S24), the data server 13 specifies the type of the occurred event (S25). This operation is repeated continuously.

  Further, the data server 13 refers to the sorting criteria 85 based on the event type 103 identified in step S25, and what is the data to be recorded for the long term according to the event type 103 (data type, data source , And recording time)), and the specified long-term recording target data is selected and read out from the short-term recording unit 65 or the work schedule 89 (S26). Then, the data server 13 stores the read long-term recording target data in the long-term recording unit 71 as an event record 93 related to the detected event (S27). The event record 93 is stored in the long-term recording unit 71 for a long time. This operation is performed each time any event defined in the detection criteria 81 is detected.

  Further, the data server 13 outputs the event record 93 stored in the long-term recording unit 71 to the outside as needed (S28).

  Further, each time the event type of the occurring event is specified in step S25, the data server 13 refers to the emergency standard 83 and determines whether the event type corresponds to the emergency event (S31). As a result, when it is determined that the event corresponds to an emergency event (Yes in S31), the data server 13 refers to the notification criteria 91, creates an emergency notification according to the event type, and carries the appropriate worker 3 It transmits to PC11 and / or peripheral object 7 (S32).

  The above-described embodiment of the present invention is merely an example for explanation, and the scope of the present invention is not limited to the embodiment. The present invention can be implemented in various forms different from the above embodiments.

  For example, various data collection devices (cameras, microphones, other various sensors, voice recognition units, etc.) and various data output devices (displays, speakers, voices, etc.) mounted on the head gear 9 and the portable PC 11 in the above embodiment, respectively. Synthesis part etc.) is only an illustration. An embodiment in which at least a part of the devices provided in the above embodiment is missing, an embodiment in which an additional device is added, an embodiment in which some or all of the functions of the portable PC 11 in the above embodiment are transferred to the headgear 9 Alternatively, various variations may be implemented, such as an embodiment in which part of the function of the headgear 9 is transferred to the portable PC 11.

  Moreover, in the said embodiment, the data acquisition system of each worker 3 is comprised from two electronic devices of the headgear 9 and portable PC9. Thereby, the headgear 9 has functions (for example, a communication function with the other mobile PC 9 and the data server 13 described later, an advanced information processing function for executing software such as voice recognition and voice synthesis at high speed) possessed by the portable PC 9. There is an advantage that the structure of the headgear 9 is simple and low in cost, since it is not necessary to double it. However, this configuration is merely an example, and other configurations may be adopted. For example, when each head worker 9 equips only the head gear 9 with the head gear 9 equipped with all the main functions of the portable PC 9. It may be sufficient. Alternatively, additional electronic devices may be added to the headgear 9 and the portable PC 9 to configure the data collection system of each worker 3.
